Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to a radio frequency adapter with a switch. Background Technology

[0002] In current RF converters, the inner conductor of the fixed end and the inner conductor of the test end are always connected. When the signal is transmitted from the fixed end to the adapter end in the non-test state, because the inner conductor of the fixed end is always connected to the inner conductor of the test end, as the frequency increases, resonance will gradually affect the overall signal transmission. Through testing of the transmission line from the fixed end to the adapter end, it is found that the voltage standing wave ratio (VSWR) data of most 3GHz or 6GHz will increase significantly (usually we consider 3GHz or 6GHz to be the cutoff frequency of the adapter). However, the application frequency and installation method requirements of electronic products on the market are getting higher and higher, and the application frequency requirement has reached as high as 12GHz. Existing RF adapters cannot reach this frequency range. Utility Model Content

[0003] Based on the above-mentioned technical problems, this application provides an RF adapter with a switch, which can greatly improve the anti-resonance capability of the entire adapter and effectively increase the product cutoff frequency to above 12GHz.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a radio frequency adapter with a switch, comprising: a housing, the housing including a test end, a fixed end and an adapter end with an internal cavity, the adapter end being disposed between the test end and the fixed end and having an upward opening;

[0005] The test end has a first inner conductor inside its cavity, which is fixed inside the test end by a first insulating medium; the adapter end has an adapter shell above it, which is installed on the opening; the adapter end has a second inner conductor inside its cavity, which is fixed inside the adapter end by a second insulating medium; the fixed end has a third inner conductor inside its cavity, which is fixed inside the fixed end by a third insulating medium.

[0006] The first inner conductor has a first spring inside, and the end of the first spring is connected to a fourth insulating medium. The end of the third inner conductor has a second spring, and the end of the second spring is connected to a movable contact pin. The movable contact pin and the fourth insulating medium are connected in an interlocking manner.

[0007] Furthermore, the movable stylus includes a movable part and a connecting part, wherein the radius of the connecting part is smaller than the radius of the movable part.

[0008] Furthermore, a circular hole is provided in the middle of the movable part, one end of the fourth insulating medium is inserted into the circular hole, and the other end abuts against the first spring.

[0009] Furthermore, when the RF adapter with switch is in a non-test state, the lower end of the second inner conductor abuts against the movable part, and the connecting part is connected to the second spring.

[0010] Furthermore, when the RF adapter with switch is in test mode, the test end moves the first inner conductor toward the fixed end under the action of the adapter. The first spring inside drives the fourth insulating medium and the movable contact pin toward the fixed end and compresses the second spring. At the same time, the lower end of the second inner conductor separates from the movable part.

[0011] Furthermore, the elastic force of the second spring is greater than that of the first spring.

[0012] Furthermore, it also includes a protective cover, which is fastened to the end face of the fixed end.

[0013] Furthermore, it also includes a retaining ring, which is installed inside the test end.

[0014] The beneficial effects of this utility model are as follows: the stability of the entire structure is ensured by adopting a double spring design inside the first inner conductor and the third inner conductor, and the coaxiality of the fixed end and the test end is ensured by setting the fourth insulating medium and the movable contact pin between the two springs. Its connected but not disconnected structural design greatly improves the anti-resonance capability of the entire adapter and effectively increases the product cutoff frequency to above 12GHz.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] This application provides an RF adapter with a switch, addressing the problem of narrow application frequency range in existing RF adapters. It should be noted that in this application, the direction of the horizontal line formed by the connection between the adapter end and the test end and the fixed end is described as "up," "above," "upper side," "upper end," "top," "top," or "top," while the opposite direction is described as "down," "lower side," "lower end," "bottom," "bottom end," or "bottom."

[0023] like Figures 1 to 5 The following is an embodiment of this application: A radio frequency adapter with a switch, comprising: a housing 10, the housing 10 including a test end 101, a fixed end 102 and an adapter end 103 with an internal cavity, the adapter end 103 being disposed between the test end 101 and the fixed end 102 and having an upward-facing opening; the test end 101 having a first inner conductor 20 in its internal cavity, the first inner conductor 20 being fixed inside the test end 101 by a first insulating medium 22; an adapter shell 42 being provided above the adapter end 103, the adapter shell 42 being mounted on the opening, the adapter end 103 having a second inner conductor 40 in its internal cavity, the second inner conductor 40 being fixed inside the adapter end 103 by a second insulating medium 41; the fixed end 102 having a third inner conductor 30 in its internal cavity, the third inner conductor 30 being fixed inside the fixed end 102 by a third insulating medium 31;

[0024] Reference Figure 3 The first inner conductor 20 has a first spring 21 inside, and the end of the third inner conductor 30 has a second spring 32. A movable contact pin 33 is provided between the two springs. Further refer to... Figure 5The movable contact pin 33 includes a movable part 330 and a connecting part 331. The movable part 330 has a circular hole 3301 in the middle. One end of the fourth insulating medium 50 is inserted into the circular hole 3301, and the other end abuts against the first spring 21. The fourth insulating medium 50 ensures the coaxiality of the fixed end 102 and the test end 101. Its connected but not disconnected structure design greatly improves the anti-resonance capability of the entire adapter and effectively raises the product cutoff frequency to above 12GHz.

[0025] Continue to refer to Figure 3 When the RF adapter is in a non-test state, the lower end of the second inner conductor 40 abuts against the movable part 330, the connecting part 331 is connected to the second spring 32, and the movable contact pin 33 is stably in contact with the second inner conductor 40 under the action of the second spring 32. The first inner conductor 20 is disconnected from the third inner conductor 30 under the action of the first spring 21, and at the same time disconnected from the second inner conductor 40, effectively reducing the resonance effect caused by the structure and realizing signal transmission from the fixed end 102 to the adapter end 103; Reference Figure 4 When the RF adapter is in test mode, the test end 101 moves the first inner conductor 20 a certain distance toward the fixed end 102 under the action of the matching head (not shown in the figure), the first spring 21 is compressed, and at this time the movable contact pin 33 is also driven to move toward the fixed end 102, the second spring 32 is also compressed, the movable contact pin 33 is disconnected from the second inner conductor 40, and the signal is transmitted from the fixed end 102 to the test end 101.

[0026] In a preferred embodiment, the elastic force of the second spring 32 is greater than that of the first spring 21. The inner conductor adopts a double spring design to ensure the stability of the entire structure. The first spring 21 ensures the disconnection between the first inner conductor 20 and the third inner conductor 30 in the non-test state. The second spring 32 ensures stable contact between the third inner conductor 30 and the second inner conductor 40. The elastic force of the second spring 32 is greater than that of the first spring 21 to ensure that the entire adapter can automatically reset.

[0027] like Figure 5 In a preferred embodiment, the radius of the connecting portion 331 is smaller than the radius of the movable portion 330, and the larger area of ​​the movable portion 330 ensures sufficient contact with the second inner conductor 40.

[0028] Reference Figure 1 In a preferred embodiment, the outer periphery of the test end 101 is provided with threads, which can be used to screw in the mating head, thereby achieving a stable connection with the mating head.

[0029] Reference Figure 2As a preferred embodiment, a protective cover 34 is also provided on the end face of the fixed end 102 to prevent dust, oil or other foreign objects from entering the connector and avoid contaminants causing poor contact or signal loss. A retaining ring 23 can also be provided inside the test end 101. The retaining ring 23 is installed inside the test end 101 and can limit the axial movement of the internal components of the test end 101 to ensure that the connector maintains structural stability during insertion, removal or vibration and avoid signal path interruption.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
